Frequently Asked Questions (FAQ)

1. What is the minimum order quantity (MOQ) for PCB assembly in Shijiazhuang or Shenzhen?

MOQs vary between factories, but many offer low MOQs of around 100-500 pieces for initial orders. Some factories may even accept smaller quantities for prototyping or low-volume production. It’s best to discuss your specific volume needs with potential factories to find the most suitable option.

2. How long does it typically take to manufacture and ship PCB assemblies from China?

Lead times depend on factors such as the complexity of the PCB design, component availability, order volume, and shipping method. In general, prototyping may take 1-2 weeks, while mass production can range from 2-6 weeks. Shipping times will depend on the chosen courier and destination, but air freight to major global cities usually takes 3-7 days.

3. Can PCB assembly factories in China source components on behalf of customers?

Yes, most PCB assembly factories in China offer component sourcing as part of their turnkey assembly services. They can procure components from their established supplier networks, which often results in cost savings and shorter lead times compared to customers sourcing components independently. However, customers should provide detailed bill of materials (BOM) and work closely with the factory to ensure the correct components are sourced.

4. How can I ensure the quality of PCB assemblies manufactured in China?

To ensure quality, choose a factory with robust quality control processes, such as automated optical inspection (AOI), X-ray inspection, in-circuit testing (ICT), and functional testing. Look for relevant quality certifications like ISO9001 and industry-specific standards. Clearly communicate your quality requirements and specifications to the factory, and consider arranging third-party inspections or factory audits for added assurance.

5. What are the payment terms and methods for PCB assembly factories in China?

Payment terms and methods can vary between factories, but common options include bank transfer (T/T), letter of credit (L/C), and online payment platforms like Alibaba Trade Assurance or PayPal. Factories may require a deposit of 30-50% upon order confirmation, with the balance paid before shipment. Some factories may offer credit terms for long-term customers with good payment history. Always clarify payment terms and methods with the factory beforehand to avoid misunderstandings.
